The Tamiya TRF 416 Aluminum Ball Differential by 3Racing (416-10) upgrades the stock unit with a rigid aluminium assembly for cleaner inputs and steadier grip. It is aimed at drivers seeking improved control during tight manoeuvres.
Made to match the TRF 416 mounting and geometry, this aluminium ball diff resists deformation better than plastic. The tighter tolerances keep power flow consistent and reduce unexpected handling changes.
This unit helps maintain a predictable balance between front and rear traction, making it easier to tune corner entry and exit. Its solid build is suitable for regular club racing and higher intensity sessions.
